P5Q PCI-E problems

[DrPepper]

I've managed to get a almost dead p5q deluxe to work and I'm stuck playing games on the pci-e 4x slot which is the only one thats working atm. Until it gets rma'd will this affect my games because Empire total war runs like crap now but benchmarks are only a few marks different.

You're effectively dividing your video card's link speed by 4... so yes you are going to experiance a nice slowdown.

I figured anyway the card died methinks, so fucking annoyed.

It will definately give you a performance hit running from 16x to 4x, but its not 1/4 because the card wouldnt take advantage of the 16x slot anyway.

Gotta remember that its a 4x PCIe 2.0 slot, so its like an 8x PCIe 1.1 slot.

I've tested this myself on a board with only a 16x slot working at 4x, and while benchmarks showed it was about half speed, games themselves were more like 1/10th.

I dont think synthetic tests show just how bad the bandwidth is needeed.

See thing is I know if its pcie 2.0 x4 it will be like a 1.1 8x slot but I don't know if it is PCI-e 2.0 I can't find any info on that slot anywhere.

The wierd thing is my 7300 works fine in the other pcie slots but the gtx260 doesn't work in them If it at least worked then I wouldn't bother RMA'ing it because its not like I can SLI on this board.

Mussels can you change the thread title please to P5Q Deluxe problems.

Also synthetic benchmarks won't overload the vram i don't think and empire total war does and it stutters like no other. Just found out the card isn't dead its my P5N-T thats dead although not tested with another GPU.

P45 is PCI-E 2.


oh and i cant rename, not a mod of this subforum.

 

[alexp999]

GPU-Z will tell you whether the slot you are running in is PCI-E 2.0 or not.

 

[DrPepper]

P45 is PCI-E 2.0

I had the idea the two x16's were 2.0 and the third was 1.1

Where about alex ?

it has THREE?

That pic says 16x @ 16x - that means 16x at 1.0/1.1

it says 2.0 in that field, if its at 2.0

 

[alexp999]

Bus Interface, that says it is running at PCI-E x16 1.1

Yeah the p5q deluxe has 3 PCI-E slots. Two that are x16 and one that is the same size as x16 but runs at x4. My gtx only works on that port for some reason.

Thanks

This is wierd because the 7300GS is running in what should be the PCI-E 2.0 slot

Here's a picture to try clarify what the setup is.

So have you just got this P5Q deluxe then and are having problems?

Mine has been the best mobo I have ever had, no joke.

Lately i've seen 5 motherboards die on me. OcUK won't rma it because they say it has bent pins. I want to like this motherboard but its so messed up it isn't funny.

 

[alexp999]

Hmm, no offence, but could it be somthing you are doing on another piece of hardware if you have had 5 boards die on you?

Have read the entire thread, but could you summarize the exact problem? Is it that one graphics card works in the PCIE-16 top slot and the other doesn't?

Nah some of those board weren't mine and some I haven't touched I meant I've seen 5 boards die. I've tested different hardware on all of them etc etc. I was beginning to think my psu might be causing it but that would only explain one board.

To summarise the GTX260 only works in the PCI-E x4 slot but other gpus work fine.

 

[alexp999]

Right here is basically how the PCI-E slots work:

What happens when you have the GTX 260 plugged into the blue PCI-E x16 slot, with no other expansion cards installed?

 

[DrPepper]

Doesn't display an image. Also with the black slot that runs at x8 there is no display.

 

[alexp999]

What bios version are you on? And does it post with just no display, or is it failing to post?

Is there a way I can tell if it does without a speaker.

I upgraded to the latest Bios from the original bios.

 

[alexp999]

So you're on 1805 I assume? and only way to tell without the onboard speaker attached is to have your PC speakers turned on and listen out for the windows start sound.

I've done that and I know how to turn winamp on without looking and there was no sound. The G15 screen never came on either and the caps lock lights etc didn't work.

 

[alexp999]

Hmm, it seems odd that the 7300GS functions in the blue slot but the GTX 260 does not.

Have you tried the GTX 260 in the middle PCI-E slot?

if caps lock doesnt work, odds are it hasnt posted. good idea there.

I think the board is completely faulty to be honest. The PCI-e 2.0's aren't being recognised as 2.0 and overclockers are being complete c**ts about it. They blame me and said I bent the pins and thats why it doesn't work.

I have and the same results. No post but the 7300GS does work.
